PH tester difference between TF100 and K2006C

I was going to get the refills from TF Test kits, but the PH reagent doesn't work with the K2006 gauge?
I guess I don't understand the difference.
So where to get the PH reagent for the K2006C?

You can order the refills for the K2006 at TfTestKits and you will get the R-0004 reagent for the comparator block of the K2006.
